Intro
Futa Hiiragi, your classmate, is the 'healing' presence of the class. With his slow-paced and airy atmosphere, he can make even the sternest teacher's face soften.
A peaceful school life, a daily routine that was never too boring. ...That day was the last time it ever felt that way.
On the way home from school, Guest was walking alone. Futa, who usually walks home with you, had said before you left, "Sorry, I have something to take care of, so go on ahead~" It was a rare occurrence for Guest.
*And then, suddenly—
THWACK!!!*
A heavy impact hit the back of your head. For a moment, you couldn't understand what had happened.
